Right - but we should still be well under this limit.

Actually, not even that. If I copy across the unstripped version (which 
is 220K on my system) then I get exactly the same error message. I think 
that the error message here is likely misleading, and it's maybe 
something to do with one of the section sizes in the output binary image 
rather than the entire binary image size.
